Should fever cover the quilt? Is it useful to cover the quilt with fever? Effect of fever on sweatin

Winter is the high incidence season of cold and fever. In the cognition of their parents' generation, they think that when the fever is not serious, they should lie at home and cover the quilt tightly. After 'covering' a sweat, the fever will naturally be fine. Can fever really be cured by 'covering the quilt'? Fever 'cover the quilt' in the end? The little editor of this article will tell you whether it is good to have a fever 'cover the quilt' and what to do with a fever.

Fever is not a disease

The normal body temperature of human body is not an absolute value. It varies slightly at different times and different parts. This difference is usually within 1 ℃. When you have a fever, you can break through this range greatly. Although the body temperature is' abnormal 'at this time, fever is actually still part of the routine regulation mechanism of body temperature.

Unlike the passive temperature rise due to heatstroke, fever is the body's active thermoregulation.

In most domestic pathology textbooks, we usually define "fever" as "fever": "fever refers to the production and release of endogenous pyrogen by endogenous pyrogen cells under the action of fever activators, which acts on the hypothalamic thermoregulatory center, and moves the temperature setting point upward mediated by the central axis fever medium, resulting in increased heat production It is a pathological process in which the heat dissipation decreases and eventually causes the body temperature to rise more than 0.5 ℃ above the normal value. "

This passage is very awkward and refers to an important concept: temperature setting point. Simply put, it is the definition of the body's' normal body temperature '. When viruses and bacteria invade or inflammation occurs in the body, the human immune system will set the standard of "normal body temperature" higher. In this way, in order to reach this new "normal body temperature", your body temperature will rise, that is, you will have a "fever".

In general, 36 ℃ - 37 ℃ is the ideal temperature for most chemical reactions in the human body. However, this is also the suitable temperature for the growth and reproduction of most bacteria and viruses. However, in the event of virus and bacterial invasion, actively raising body temperature can inhibit the vitality of bacteria and viruses, accelerate the proliferation and movement of leukocytes, and improve the combat ability of the immune system. This is why the human body actively raises the temperature setting point.

Fever is not a disease, but a symptom, and it is beneficial in most cases.

Sweat is not covered

Due to the upward movement of the temperature setting point, the human body will judge that its current body temperature is too low. In order to quickly increase its temperature, the human body will have a series of reactions: epidermal vasoconstriction, sweat gland inhibition to reduce heat dissipation, muscle tremor to increase heat production (shivering). This is the symptom of most people in the early stage of fever: cold.

When the body temperature rises to the new temperature setting point, it enters the second stage of fever: high temperature duration. The heat production and heat dissipation of the human body reach a relative balance at a high level, and the body temperature fluctuates at a high level. At this time, people will experience continuous heat, dry skin and lips, which is the most uncomfortable stage in the whole process of fever. At this time, leukocytes increase rapidly and the immune system is fully open.

After the pyrogen causing fever is solved, the thermoregulation center will reset the temperature setting point and return to the daily level. At this time, it enters the antipyretic period in the process of fever. At this time, the human body often sweats a lot in order to quickly reduce the body temperature. When the body temperature drops to the new temperature setting point, the fever process is basically over.

The above is a description of a typical 'fever - fever reduction' process. From which we can see that sweating is the result of antipyretic rather than the cause. The so-called 'covering sweat' antipyretic is entirely a fruitless cause. If the heat source (virus, bacteria) is not solved, how to cover people will not sweat. If you are not aware of this, you attribute the fever reduction to covering sweat, and even think that the tighter the cover, the better the effect, it may lead to serious consequences, such as' baby covering heat syndrome '.

This disease is mainly caused by keeping children too warm or covering them for too long. According to the clinical research report published in the Journal of Changzhi Medical College, among 128 such children, 59 cases had multiple organ function damage, with an incidence of 46.09%, of which 25 cases (42.37%) had one system damage, 31 cases (52.54%) had two system damage, and 3 cases (5.09%) had three system damage. 55 cases were completely cured and left sequelae to varying degrees (such as mental retardation, cerebral palsy, epilepsy, etc.) 3 cases, 1 case died.

The real meaning of covering sweat

In the early stage of fever (shivering period), people will experience the rise of body temperature. At this time, covering the quilt is conducive to suppressing the heat dissipation on the body surface and making the process of heating up a little faster.

But this is not the fundamental reason why the Chinese insist on covering their sweat.

In the early stage of fever, the typical symptom is chilly. At normal room temperature, it will tremble and fight. Even without the guidance of old traditional Chinese medicine, normal people's reaction at this time is to strengthen warmth preservation. Covering the quilt can effectively alleviate the chilly symptoms in the early stage of fever, which is the root of its recognition.

In addition to covering sweat, the traditional way to deal with fever is to drink ginger soup and hot water. They bring some warm comfort when we shiver. As mentioned above, fever is not the disease itself, but a symptom. In most cases, even without any treatment, the fever symptoms will disappear after a certain time. People with fever are not necessarily ill, usually It's just uncomfortable. The practical significance of all fever reduction methods is to make people feel more comfortable. If covering the quilt can really make you feel better, cover it.

However, covering sweat is only limited to the early stage of fever. When the fever enters the high-temperature duration, the human body will feel continuously hot and dry mouth. At this time, what to do is to quickly carry out physical cooling. Not only can the quilt not be covered, but also wear less clothes. If necessary, local ice compress and other cooling measures can be taken. High fever still continues to cover sweat, which is a kind of self abuse.

Guard against high fever

As mentioned above, fever actually helps to improve the combat effectiveness of the immune system. Does that mean that fever is a symptom that does not need intervention?

In most low and medium temperature fevers, people can heal themselves. However, they will bring discomfort to people at all stages of fever: cold in the shivering period, extreme heat in the peak period, headache and dehydration in the antipyretic period & hellip; & hellip; even high fever at 38 ℃ and 9 ℃ will not cause actual damage to organs. The most frightening consequences caused by simple fever may be caused by nervous system disorders Convulsions, convulsions.

According to the data of the National Institute of neurological diseases and stroke, 4% of newborns will encounter this problem. Although most of them will disappear naturally and will not leave any sequelae, parents will be scared. Artificial intervention for fever is mainly to alleviate the discomfort of fever patients or appease caregivers.

However, persistent fever is still a signal that needs attention. As mentioned earlier, fever is only a symptom. In English, fever is called fever, and many diseases can lead to fever: yellow fever, typhoid fever, scarlet fever & hellip; & hellip;

The causes of long-term fever vary in different years and regions, but the main three categories are infection, malignant tumor and connective tissue disease, accounting for about 90% of the causes of long-term fever. Almost all infectious diseases can cause recurrent fever, such as malaria, returnable fever, Kala Azar, brucellosis, urinary tract infection, lymphoma, etc.

A long-term fever shows that the immune system is powerless to the pyrogen and needs to see a doctor in time to find out the pyrogen and treat the symptoms. In this case, no matter how to cover the quilt, there is no sweat, which will only keep the high fever and delay the timely treatment of the disease, that is, the 'fever turns into pneumonia / encephalitis' in many populations.
